Abstract

The title cluster compound, [Ru3(C19H17PS)(CO)11], comprises a triangle of Ru0 atoms, two of which are bonded to four carbonyl ligands. The third metal atom is
bound to three carbonyl ligands and the phosphane-P atom of a dissymmetric phosphane ligand, PPh2(C6H4SMe-4); no Ru� � �S interactions are observed. The phosphane occupies an equatorial position and its proximity to an Ru—Ru edge
results in the elongation of this bond with respect to the others [2.8933 (2) A ° cf. 2.8575 (2) and 2.8594 (3) A ° ]. In the crystal, phenyl-C—H...�O(carbonyl) and
carbonyl-O� � �O(carbonyl) [2.817 (2) A ° ] interactions combine to form a supramolecular chain propagating along [111]; the chains pack without directional
interactions between them. The carbonyl-O...�O(carbonyl) and other weak contacts have an influence upon the Hirshfeld surfaces with O...�H contacts making the greatest contribution, i.e. 37.4% cf. 15.8% for O� � �O and 15.6% for
H� � �H contacts.
